That is, the tip of the seedling-transplanting nail 36 corresponds to the transplant locus P.
, And the seedlings successively fed to the seedling dividing ports 27 of the seedling receiving plate 26 are divided in the seedling tank 20 that reciprocates left and right, and the seedlings are successively transferred to the field scene. When the seedling is pushed into the lowermost soil surface (at the position P1), the seedling pushing fork 37 pushes the seedling downward by the action of the spring 40 and transplants it.

Then, the 2 attached to the rotating case 29
When there is a difference in the amount of seedling division by the seedling transplanting claws 36 of the base transplanting tool 35 or when the seedling transplanting posture is poor, the transplanting device main body 35a is rotationally adjusted with respect to the transplanting device drive shaft 34, The size and angle at which the seedling transfer nail 36 intervenes in the seedling division opening 27 may be adjusted. In this adjustment, bolt 4
It is sufficient to adjust the mounting angle between the mounting member 42 and the implanting device main body 35a by loosening the fitting 3, but since this adjustment can be performed outside the implanting device main body 35a, the operation can be extremely easily performed.

If the seedling transplanting nail 36 is displaced laterally with respect to the seedling dividing port 27 of the seedling receiving plate 26 at the time of dividing the seedling, the cotter pin 44 is loosened and the transplanter main body 35a is loosened.
May be adjusted in the axial direction by driving the cotter pin 44 again. The rotating member 60 is also rotated by the rotation of the rotating case 29 by the seedling transplanting operation, and the feeding roll 52 of the fertilizer feeding unit 49 is rotated via the connecting rod 65, the arm 67, and the one-way clutch, and the fertilizer is moved into the fertilizer transferring unit 50. To fall. On the other hand, even if the driving rotary disk 58 rotates via the transmission belt 74 and the driven pulley 71 and the straw or the like floats on the field, the straw is properly embedded in the soil to form a groove on the soil surface. Since the fertilizer is formed, the fertilizer that has fallen in the fertilizer transfer unit 50 is properly applied in the groove, and is always applied to an appropriate uniform depth. Then, the fertilized grooves are backfilled with the earth covering plate 75, and the soil surface is flattened. However, fertilizer application is performed simultaneously with seedling transplantation.

In particular, the rotation drive shaft 28 of the rotation member 60 which is bridged between the plurality of implanting tools 35 provided on the rotation case 29 and rotates in the same direction as the rotation case 29 is eccentric. Since the lower end of the driving member 64 for driving the fertilizer feeding section 49 is mounted at the position,
The fertilizer feeding unit 49 of the fertilizer applicator 46 can be driven by the rotating member 60 that rotates smoothly in the same direction as the rotating case 29, and there is no need to separately provide a drive system dedicated to the fertilizer feeding unit 49 on the machine body. Fertilizer feeding section 49 with structure
, And good fertilization work and rice transplanting work can be performed.

In the above embodiment, the rotary kerf 5
Although only one of the discs 58 and 59 is provided to be driven and rotated, both discs 58 and 59 may be provided to be driven and rotated by the rotary case 29.
